Update files to match the opus-1.0.0 source release. This corresponds to the spec implementation included in RFC 6716. Changes from the previous in-tree version (draft-12): - Add extern "C" protection on opus_multistream.h. - Align to sizeof(void*) instead of 4 bytes. - Copyright header updates for IETF publication. - Minor documentation and whitespace fixes.
